VENUS ele-an.s. 

 TAB. CCCCXXIL— >V>^. 3. 

 Spec. Char. Ovate, convex, transversely 

 sulcated ; lunette ovate ; the spaces be- 

 tween the sulci rounded and shining. 

 Sv^f . Venus gallina, Brancler Jig. 90, excl. Syn. 

 Linn, et forte Jig. 94. Cytherea elegans, 

 Lamarck env. de Paris, 232. 



A RATHER depressed shinin*^ shell precisely like the 

 Gjy. ericinoides of Lamarck (Hist. Nat. Vol. V. p. 581.) 

 hut consideral)ly smaller ; it is probably therefore his 

 O. elegans, although it is too ovate to agree with his 

 description ; it agrees better Avith his figure in the 

 Annales du Museum : the sulci upon its surface are few, 

 deep, sharp at their bases with rounded edges ; the 

 posterior side is small, a very little rounder than the 

 other ; tlie lunette is also small ; the beaks are but 

 slightly prominent. 



One of the less common, although not a scarce Barton 

 Fossil. What Brander's fig. 94 is, must still remain a 

 question ; it must be a badly chosen view, if it be from 

 a variety of tliis species. 



VENUS? pectenifera. 



TAB. CCCCXXII.— j%. 4. 



Spec. Char. Transversely oblong, carinated ; 

 surface longitudinally sulcated, and sup- 

 porting a few erect lamellae, commencing at 

 the keel ; anterior side smooth, truncated. 



_Lhis elegant shell has about four erect, rather thick 

 lamella?, that rise from the keel which defines the smooth 

 anterior side, and curve over the rest of the disk ; they 

 are striated upon their lower sides, so as to resemble 

 combs. 



So rare is this species, that only a single valve has 

 been found at Barton, although it has been particularly 

 sought after for several years : the hinge teeth are 

 broken away, so that the Genus is left doubtful ; it 

 lias much the appearance of a Crassatella. 



From the valuable collection of Lord Fitzharris.
